Green tea consumption and cognitive function: a cross-sectional study from the Tsurugaya Project
Background: Although considerable experimental and animal evidence shows that green tea may possess potent activities of neuroprotection, neurorescue, and amyloid precursor protein processing that may lead to cognitive enhancement, no human data are available.
Objective: The objective was to examine the association between green tea consumption and cognitive function in humans.
Design: We analyzed cross-sectional data from a community-based Comprehensive Geriatric Assessment (CGA) conducted in 2002. The subjects were 1003 Japanese subjects aged ≥70 y. They completed a self-administered questionnaire that included questions about the frequency of green tea consumption. We evaluated cognitive function by using the Mini-Mental State Examination with cutoffs of <28, <26, and
Results: Higher consumption of green tea was associated with a lower prevalence of cognitive impairment. At the
Conclusion: A higher consumption of green tea is associated with a lower prevalence of cognitive impairment in humans.
